Abstract
The utility model discloses a friction wheel, which includes a wheel seat, wherein a lug boss is arranged in the middle of the wheel seat; a through hole is formed in the lug boss; wheel seat holes are formed in the wheel seat; semi-circular grooves are formed on the lower seat surface of the wheel seat; and propping blocks are fixed in the semi-circular grooves through elastic components. The friction wheel has a simple structure, is easy to realize, can effectively increase the friction force of the friction wheels, and avoid that the friction wheels slip away from each other.
Description
Technical field
The utility model relates to the friction driving field, is specially a kind of friction wheel.
Background technique
The friction wheel transmission is made up of two cylindrical friction wheels that compress each other, and when proper functioning, driving wheel can drive the follower revolution by function of friction, and makes transmission keep the rotation ratio of fixing basically.The frictional force size is determining the performance of friction wheel between the friction wheel, and existing technology is the coarse processing of wheel face that friction wheel is in contact with one another, with increase frictional force, but still the phenomenon that can occur skidding each other.
The model utility content
The purpose of the utility model provides a kind of friction wheel, to solve the mutual problem of slip of existing technology friction wheel.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of friction wheel includes wheel seat, it is characterized in that: said wheel seat intermediate portion forms the boss protruding with respect to seat surface on the wheel seat; Have the through hole that runs through wheel seat in the middle of the said boss; And the upper and lower end of through hole is respectively the hole face of hole enlargement, around also having a plurality of wheel seats hole in the wheel seat of boss, is positioned at that seat surface also forms a plurality of half slots under the said wheel seat; Be provided with the piece that supports a little more than seat surface under the wheel seat in the said half slot, the said piece that supports is fixed in the half slot through elastic component.
The utility model is simple in structure, is easy to realize, through at the wheel seat seat surface half slot being set; Insert the piece that supports in the half slot a little more than the wheel seat seat surface; Support piece and be fixed in the half slot, when such two friction wheel wheel faces contact and mutual extrusion, can make to piece through elastic component the other side's friction wheel is exerted pressure through elastic component; Can increase the frictional force between the friction wheel effectively, avoid occurring mutual problem of slip between the friction wheel.
Description of drawings
Fig. 1 is the utility model structure side sectional view.
Embodiment
As shown in Figure 1.A kind of friction wheel includes wheel seat 1, and wheel seat 1 intermediate portion forms the boss 2 protruding with respect to seat surface on the wheel seat 1; Have the through hole 3 that runs through wheel seat 1 in the middle of the boss 2; And the upper and lower end of through hole 3 is respectively the hole face of hole enlargement, also has a plurality of wheel seats hole 4 in the wheel seat 1 around boss 2, is positioned at 1 time seat surface of wheel seat and also forms a plurality of half slots 5; Be provided with in the half slot 5 a little more than 1 time seat surface of wheel seat support piece 6, support piece 6 and be fixed in the half slot 5 through elastic component 7.
